Volume Iii Part 5 (1/2)

The average price is 14 reals and varies from 10 to 18 (the real is worth about 6 1/2 pence English). M. Urquinasa estimates the total exportation of Venezuela in 1809 at 200,000 arrobas of tasajo.) It is not from the advancement of agriculture or the progressive encroachments on the pastoral lands that the hatos (herds and flocks) have diminished so considerably within twenty years; it is rather owing to the disorders of every kind that have prevailed, and the want of security for property. The impunity conceded to the skin-stealers and the acc.u.mulation of marauders in the savannahs preceded that destruction of cattle caused by the ravages of civil war and the supplies required for troops. A very considerable number of goat-skins is exported to the island of Marguerita, Punta Araya and Corolas; sheep abound only in Carora and Tocuyo. The consumption of meat being immense in this country the diminution of animals has a greater influence here than in any other district on the well-being of the inhabitants. The town of Caracas, of which the population in my time was one-tenth of that of Paris, consumed more than one-half the quant.i.ty of beef annually used in the capital of France.

I might add to the productions of the vegetable and animal kingdoms of Venezuela the enumeration of the minerals, the working of which is worthy the attention of the government; but having from my youth been engaged in the practical labours of mines I know how vague and uncertain are the judgments formed of the metallic wealth of a country from the mere appearance of the rocks and of the veins in their beds.

The utility of such labours can be determined only by well directed experiments by means of shafts or galleries. All that has been done in researches of this kind, under the dominion of the mother-country, has left the question wholly undecided and the most exaggerated ideas have been recently spread through Europe concerning the riches of the mines of Caracas. The common denomination of Columbia given to Venezuela and New Grenada has doubtless contributed to foster those illusions. It cannot be doubted that the gold-was.h.i.+ngs of New Grenada furnished, in the last years of public tranquillity, more than 18,000 marks of gold; that Choco and Barbacoa supply platinum in abundance; the valley of Santa Rosa in the province of Antioquia, the Andes of Quindiu and Gauzum near Cuenca, yield sulphuretted mercury; the table-land of Bogota (near Zipaquira and Canoas), fossil-salt and pit-coal; but even in New Grenada subterranean labours on the silver and gold veins have hitherto been very rare. I am far, however, from wis.h.i.+ng to discourage the miners of those countries: I merely conceive that for the purpose of proving to the old world the political importance of Venezuela, the amazing territorial wealth of which is founded on agriculture and the produce of pastoral life, it is not necessary to describe as realities, or as the acquisitions of industry, what is, as yet, founded solely on hopes and probabilities more or less uncertain. The republic of Columbia also possesses on its coast, on the island of Marguerita, on the Rio Hacha and in the gulf of Panama pearl fisheries of ancient celebrity. In the present state of things, however, fis.h.i.+ng for these pearls is an object of as little importance as the exportation of the metals of Venezuela. The existence of metallic veins on several points of the coast cannot be doubted. Mines of gold and silver were worked at the beginning of the conquest at Buria, near Barquesimeto, in the province of Los Mariches, at Baruta, on the south of Caracas, and at Real de Santa Barbara near the Villa de Cura.

Grains of gold are found in the whole mountainous territory between Rio Yaracuy, the Villa de San Felipe and Nirgua, as well as between Guigue and Los Moros de San Juan. M. Bonpland and myself, during our long journey, saw nothing in the gneiss granite of Spanish Guiana to confirm the old faith in the metallic wealth of that district; yet it seems certain from several historical notices that there exist two groups of auriferous alluvial land; one between the sources of the Rio Negro, the Uaupes and the Iquiare; the other between the sources of the Essequibo, the Caroni and the Rupunuri. Hitherto only one working is found in Venezuela, that of Aroa: it furnished, in 1800, near 1500 quintals of copper of excellent quality. The green-stone rocks of the transition mountains of Tucutunemo (between Villa de Cura and Parapara) contain veins of malachite and copper pyrites. The indications of both ochreous and magnetic iron in the coast-chain, the native alum of Chuparipari, the salt of Araya, the kaolin of the Silla, the jade of the Upper Orinoco, the petroleum of Buen-Pastor and the sulphur of the eastern part of New Andalusia equally merit the attention of the government.

It is easy to ascertain the existence of some mineral substances which afford hopes of profitable working but it requires great circ.u.mspection to decide whether the mineral be sufficiently abundant and accessible to cover the expense.* (* In 1800 a day-labourer (peon) employed in working the ground gained in the province of Caracas 15 sous, exclusive of his food. A man who hewed building timber in the forests on the coast of Paria was paid at c.u.mana 45 to 50 sous a day, without his food. A carpenter gained daily from 3 to 6 francs in New Andalusia. Three cakes of ca.s.sava (the bread of the country), 21 inches in diameter, 1 1/2 lines thick, and 2 1/2 pounds weight, cost at Caracas one half-real, or 6 1/2 sous. A man eats daily not less than 2 sous' worth of ca.s.sava, that food being constantly mixed with bananas, dried meat (tasajo) and panelon, or unrefined sugar.) Even in the eastern part of South America gold and silver are found dispersed in a manner that surprises the European geologist; but that dispersion, together with the divided and entangled state of the veins and the appearance of some metals only in ma.s.ses, render the working extremely expensive. The example of Mexico sufficiently proves that the interest attached to the labours of the mines is not prejudicial to agricultural pursuits, and that those two branches of industry may simultaneously promote each other. The failure of the attempts made under the intendant, Don Jose Avalo, must be attributed solely to the ignorance of the persons employed by the Spanish government who mistook mica and hornblende for metallic substances. If the government would order the Capitania-General of Caracas to be carefully examined during a series of years by men of science, well versed in geognosy and chemistry, the most satisfactory results might be expected.

The description above given of the productions of Venezuela and the development of its coast sufficiently shows the importance of the commerce of that rich country. Even under the thraldom of the colonial system, the value of the exported products of agriculture and of the gold-was.h.i.+ngs amount to eleven or twelve millions of piastres in the countries at present united under the denomination of the Republic of Columbia. The exports of the Capitania-General of Caracas alone, exclusive of the precious metals which are the objects of regular working, was (with the contraband) from five to six millions of piastres at the beginning of the nineteenth century. c.u.mana, Barcelona, La Guayra, Porto Cabello and Maracaybo are the most important parts of the coast; those that lie most eastward have the advantage of an easier communication with the Virgin Islands, Guadaloupe, Martinique and St. Vincent. Angostura, the real name of which is Santo Tome de Nueva Guiana, may be considered as the port of the rich province of Varinas. The majestic river on whose banks this town is built, affords by its communications with the Apure, the Meta and the Rio Negro the greatest advantages for trade with Europe.

The sh.o.r.es of Venezuela, from the beauty of their ports, the tranquillity of the sea by which they are washed and the fine timber that covers them, possess great advantages over the sh.o.r.es of the United States. In no part of the world do we find firmer anchorage or better positions for the establishment of ports. The sea of this coast is constantly calm, like that which extends from Lima to Guayaquil.

The storms and hurricanes of the West Indies are never felt on the Costa Firme; and when, after the sun has pa.s.sed the meridian, thick clouds charged with electricity acc.u.mulate on the mountains of the coasts, a pilot accustomed to these lat.i.tudes knows that this threatening aspect of the sky denotes only a squall. The virgin-forests near the sea, in the eastern part of New Andalusia, present valuable resources for the establishment of dockyards. The wood of the mountains of Paria may vie with that of the island of Cuba, Huasacualco, Guayaquil and San Blas. The Spanish Government at the close of the last century fixed its attention on this important object. Marine engineers were sent to mark the finest trunks of Brazil-wood, mahogany, cedrela and laurinea between Angostura and the mouth of the Orinoco, as well as on the banks of the Gulf of Paria, commonly called the Golfo triste. It was not intended to establish docks on that spot, but to hew the weighty timber into the forms necessary for s.h.i.+p-building, and to transport it to Caraque, near Cadiz. Though trees fit for masts are not found in this country, it was nevertheless hoped that the execution of this project would considerably diminish the importation of timber from Sweden and Norway. The experiment of forming this establishment was tried in a very unhealthy spot, the valley of Quebranta, near Guirie; I have already adverted to the causes of its destruction. The insalubrity of the place would, doubtless, have diminished in proportion as the forest (el monte virgen) should have been removed from the dwellings of the inhabitants. Mulattos, and not whites, ought to have been employed in hewing the wood, and it should have been remembered that the expense of the roads (arastraderos) for the transport of the timber, when once laid out, would not have been the same, and that, by the increase of the population, the price of day labour would progressively have diminished. It is for s.h.i.+p-builders alone, who determine the localities, to judge whether, in the present state of things, the freight of merchant-vessels be not far too high to admit of sending to Europe large quant.i.ties of roughly-hewn wood; but it cannot be doubted that Venezuela possesses on its maritime coast, as well as on the banks of the Orinoco, immense resources for s.h.i.+p-building. The fine s.h.i.+ps which have been launched from the dockyards of the Havannah, Guayaquil and San Blas have, no doubt, cost more than those constructed in Europe; but from the nature of tropical wood they possess the advantages of hardness and amazing durability.

The great struggle during which Venezuela has fought for independence has lasted more than twelve years. That period has been no less fruitful than civil commotions usually are in heroic and generous actions, guilty errors and violent pa.s.sions. The sentiment of common danger has strengthened the ties between men of various races who, spread over the plains of c.u.mana or insulated on the table-land of Cundinamarca, have a physical and moral organization as different as the climates in which they live. The mother-country has several times regained possession of some districts; but as revolutions are always renewed with more violence when the evils that produce them can no longer be remedied these conquests have been transitory. To facilitate and give greater energy to the defence of this country the governments have been concentrated, and a vast state has been formed, extending from the mouth of the Orinoco to the other side of the Andes of Riobamba and the banks of the Amazon. The Capitania-General of Caracas has been united to the Vice-royalty of New Grenada, from which it was only separated entirely in 1777. This union, which will always be indispensable for external safety, this centralization of powers in a country six times larger than Spain, has been prompted by political views. The tranquil progress of the new government has justified the wisdom of those views, and the Congress will find still fewer obstacles in the execution of its beneficent projects for national industry and civilization, in proportion as it can grant increased liberty to the provinces, must render the people sensible to the advantages of inst.i.tutions which they have purchased at the price of their blood. In every form of government, in republics as well as in limited monarchies, improvements, to be salutary, must be progressive.

New Andalusia, Caracas, Cundinamarca, Popayan and Quito, are not confederate states like Pennsylvania, Virginia and Maryland. Without juntas, or provincial legislatures, all those countries are directly subject to the congress and government of Columbia. In conformity with the const.i.tutional act, the intendants and governors of the departments and provinces are nominated by the president of the republic. It may be naturally supposed that such dependence has not always been deemed favourable to the liberty if the communes, which love to discuss their own local interests. The ancient kingdom of Quito, for instance, is connected by the habits and language of its mountainous inhabitants with Peru and New Grenada. If there were a provincial junta, if the congress alone determined the taxes necessary for the defence and general welfare of Columbia, the feeling of an individual political existence would render the inhabitants less interested in the choice of the spot which is the seat of the central government. The same argument applies to New Andalusia or Guiana which are governed by intendants named by the president. It may be said that these provinces have hitherto been in a position differing but little from those territories of the United States which have a population below 60,000 souls. Peculiar circ.u.mstances, which cannot be justly appreciated at such a distance, have doubtless rendered great centralization necessary in the civil administration; every change would be dangerous as long as the state has external enemies; but the forms useful for defence are not always those which, after the struggle, sufficiently favour individual liberty and the development of public prosperity.

The powerful union of North America has long been insulated and without contact with any states having a.n.a.logous inst.i.tutions.

Although the progress America is making from east to west is considerably r.e.t.a.r.ded near the right bank of the Mississippi, she will advance without interruption towards the internal provinces of Mexico, and will there find a European people of another race, other manners, and a different religious faith. Will the feeble population of those provinces, belonging to another dawning federation, resist; or will it be absorbed by the torrent from the east and transformed into an Anglo-American state, like the inhabitants of Lower Louisiana? The future will soon solve this problem. On the other hand, Mexico is separated from Columbia only by Guatimala, a country and extreme fertility which has recently a.s.sumed the denomination of the republic of Central America. The political divisions between Oaxaca and Chiapa, Costa Rica and Veragua, are not founded either on the natural limits or the manners and languages of the natives, but solely on the habit of dependence on the Spanish chiefs who resided at Mexico, Guatimala or Santa Fe de Bogota. It seems natural that Guatimala should one day join the isthmuses of Veragua and Panama to the isthmus of Costa Rica; and that Quito should connect New Grenada with Peru, as La Paz, Charcas and Potosi link Peru with Buenos-Ayres. The intermediate parts from Chiapa to the Cordilleras of Upper Peru form a pa.s.sage from one political a.s.sociation to another, like those transitory forms which link together the various groups of the organic kingdom in nature. In neighbouring monarchies the provinces that adjoin each other present those striking demarcations which are the effect of great centralization of power in federal republics, states situated at the extremities of each system are some time before they acquire a stable equilibrium. It would be almost a matter of indifference to the provinces between Arkansas and the Rio del Norte whether they send their deputies to Mexico or to Was.h.i.+ngton. Were Spanish America one day to show a more uniform tendency towards the spirit of federalism, which the example of the United States has created on several points, there would result from the contact of so many systems or groups of states, confederations variously graduated. I here only touch on the relations that arise from this a.s.semblage of colonies on an uninterrupted line of 1600 leagues in length. We have seen in North America, one of the old Atlantic states divided into two, and each having a different representation. The separation of Maine and Ma.s.sachusetts in 1820 was effected in the most peaceable manner.

Schisms of this kind will, it may be feared, render such changes turbulent. It may also be observed that the importance of the geographical divisions of Spanish America, founded at the same time on the relations of local position and the habits of several centuries, have prevented the mother-country from r.e.t.a.r.ding the separation of the colonies by attempting to establish Spanish princes in the New World.

In order to rule such vast possessions it would have been requisite to form six or seven centres of government; and that multiplicity of centres was hostile to the establishment of new dynasties at the period when they might still have been salutary to the mother country.

Bacon somewhere observes that it would be happy if nations would always follow the example of time, the greatest of all innovators, but who acts calmly and almost without being perceived. This happiness does not belong to colonies when they reach the critical juncture of emanc.i.p.ation; and least of all to Spanish America, engaged in the struggle at first not to obtain complete independence, but to escape from a foreign yoke. May these party agitations be succeeded by a lasting tranquillity! May the germ of civil discord, disseminated during three centuries to secure the dominion of the mother-country, gradually perish; and may productive and commercial Europe be convinced that to perpetuate the political agitations of the New World would be to impoverish herself by diminis.h.i.+ng the consumption of her productions and losing a market which already yields more than seventy millions of piastres. Many years must no doubt elapse before seventeen millions of inhabitants, spread over a surface one-fifth greater than the whole of Europe, will have found a stable equilibrium in governing themselves. The most critical moment is that when nations, after long oppression, find themselves suddenly at liberty to promote their own prosperity. The Spanish Americans, it is unceasingly repeated, are not sufficiently advanced in intellectual cultivation to be fitted for free inst.i.tutions. I remember that at a period not very remote, the same reasoning was applied to other nations who were said to have made too great an advance in civilization. Experience, no doubt, proves that nations, like individuals, find that intellect and learning do not always lead to happiness; but without denying the necessity of a certain ma.s.s of knowledge and popular instruction for the stability of republics or const.i.tutional monarchies, we believe that stability depends much less on the degree of intellectual improvement than on the strength of the national character; on that balance of energy and tranquillity of ardour and patience which maintains and perpetuates new inst.i.tutions; on the local circ.u.mstances in which a nation is placed; and on the political relations of a country with neighbouring states.

CHAPTER 3.28.

Pa.s.sAGE FROM THE COAST OF VENEZUELA TO THE HAVANNAH.

GENERAL VIEW OF THE POPULATION OF THE WEST INDIA ISLANDS, COMPARED WITH THE POPULATION OF THE NEW CONTINENT, WITH RESPECT TO DIVERSITY OF RACES, PERSONAL LIBERTY, LANGUAGE, AND WORs.h.i.+P.

We sailed from Nueva Barcelona on the 24th of November at nine o'clock in the evening; and we doubled the small rocky island of Borachita.

The night was marked by coolness which characterizes the nights of the tropics, and the agreeable effect of which can only be conceived by comparing the nocturnal temperature, from 23 to 24 degrees centigrade, with the mean temperature of the day, which in those lat.i.tudes is generally, even on the coast, from 28 to 29 degrees. Next day, soon after the observation of noon, we reached the meridian of the island of Tortugas. It is dest.i.tute of vegetation; and like the little islands of Coche and Cabagua is remarkable for its small elevation above the level of the sea.

In the forenoon of the 26th we began to lose sight of the island of Marguerita and I endeavoured to verify the height of the rocky group of Macanao. It appeared under an angle of 0 degrees 16 minutes 35 seconds; which in a distance estimated at sixty miles would give the mica-slate group of Macanao the elevation of about 660 toises, a result which, in a zone where the terrestrial refractions are so unchanging, leads me to think that the island was less distant than we supposed. The dome of the Silla of Caracas, lying 62 degrees to the south-west, long fixed our attention. At those times when the coast is not loaded with vapours the Silla must be visible at sea, without reckoning the effects of refraction, at thirty-three leagues distance.

During the 26th, and the three following days, the sea was covered with a bluish film which, when examined by a compound microscope, appeared formed of an innumerable quant.i.ty of filaments. We frequently find these filaments in the Gulf-stream, and the Channel of Bahama, as well as near the coast of Buenos Ayres. Some naturalists are of opinion that they are vestiges of the eggs of mollusca: but they appear to be more like fragments of fuci. The phosph.o.r.escence of sea-water seems however to be augmented by their presence, especially between 28 and 30 degrees of north lat.i.tude, which indicates an origin of some sort of animal nature.

On the 27th we slowly approached the island of Orchila. Like all the small islands in the vicinity of the fertile coast of the continent it has never been inhabited. I found the lat.i.tude of the northern cape 11 degrees 51 minutes 44 seconds and the longitude of the eastern cape 68 degrees 26 minutes 5 seconds (supposing Nueva Barcelona to be 67 degrees 4 minutes 48 seconds). Opposite the western cape there is a small rock against which the waves beat turbulently. Some angles taken with the s.e.xtant gave, for the length of the island from east to west, 8.4 miles (950 toises); and for the breadth scarcely three miles. The island of Orchila which, from its name, I figured to myself as a bare rock covered with lichens, was at that period beautifully verdant. The hills of gneiss were covered with gra.s.ses. It appears that the geological const.i.tution of Orchila resembles, on a small scale, that of Marguerita. It consists of two groups of rocks joined by a neck of land; it is an isthmus covered with sand which seems to have issued from the floods by the successive lowering of the level of the sea.

The rocks, like all those which are perpendicular and insulated in the middle of the sea, appear much more elevated than they really are, for they scarcely exceed from 80 to 90 toises. The Punta rasa stretches to the north-west and is lost, like a sandbank, below the waters. It is dangerous for navigators, and so is likewise the Mogote which, at the distance of two miles from the western cape, is surrounded by breakers. On a very near examination of these rocks we saw the strata of gneiss inclined towards the north-west and crossed by thick layers of quartz. The destruction of these layers has doubtless created the sands of the surrounding beach. Some clumps of trees shade the valleys, the summits of the hills are crowned with fan-leaved palm-trees; probably the palma de sombrero of the Llanos (Corypha tectorum). Rain is not abundant in these countries; but probably some springs might be found on the island of Orchila if sought for with the same care as in the mica-slate rocks of Punta Araya. When we recollect how many bare and rocky islands are inhabited and cultivated between the 17th and 26th degrees of lat.i.tude in the archipelago of the Lesser Antilles and Bahama islands, we are surprised to find those islands desert which are near to the coast of c.u.mana, Barcelona and Caracas.

They would long have ceased to be so had they been under the dominion of any other government than that to which they belong. Nothing can engage men to circ.u.mscribe their industry within the narrow limits of a small island when a neighbouring continent offers them greater advantages.

We perceived at sunset the two points of the Roca de afuera, rising like towers in the midst of the ocean. A survey taken with the compa.s.s placed the most easterly of the points or roques at 0 degrees 19 minutes west of the western cape of Orchila. The clouds continued long acc.u.mulated over that island and showed its position from afar. The influence of a small tract of land in condensing the vapours suspended at an elevation of 800 toises is a very extraordinary phenomenon, although familiar to all mariners. From this acc.u.mulation of clouds the position of the lowest island may be recognized at a great distance.

On the 29th November we still saw very distinctly, at sunrise, the summit of the Silla of Caracas just rising above the horizon of the sea. At noon everything denoted a change of weather in the direction of the north: the atmosphere suddenly cooled to 12.6 degrees, while the sea maintained a temperature of 25.6 degrees at its surface. At the moment of the observation of noon the oscillations of the horizon, crossed by streaks or black bands of very variable size, produced changes of refraction from 3 to 4 degrees. The sea became rough in very calm weather and everything announced a stormy pa.s.sage between Cayman Island and Cape St. Antonio. On the 30th the wind veered suddenly to north-north-east and the surge rose to a considerable height. Northward a darkish blue tint was observable on the sky, the rolling of our small vessel was violent and we perceived amidst the das.h.i.+ng of the waves two seas crossing each other, one the from north and the other from north-north-east. Waterspouts were formed at the distance of a mile and were carried rapidly from north-north-east to north-north-west. Whenever the waterspout drew near us we felt the wind grow sensibly cooler. Towards evening, owing to the carelessness of our American cook, our deck took fire; but fortunately it was soon extinguished. On the morning of the 1st of December the sea slowly calmed and the breeze became steady from north-east. On the 2nd of December we descried Cape Beata, in a spot where we had long observed the clouds gathered together. According to the observations of Acherner, which I obtained in the night, we were sixty-four miles distant. During the night there was a very curious optical phenomenon, which I shall not undertake to account for. At half-past midnight the wind blew feebly from the east; the thermometer rose to 23.2 degrees, the whalebone hygrometer was at 57 degrees. I had remained upon the deck to observe the culmination of some stars. The full-moon was high in the heavens. Suddenly, in the direction of the moon, 45 degrees before its pa.s.sage over the meridian, a great arch was formed tinged with the prismatic colours, though not of a bright hue. The arch appeared higher than the moon; this iris-band was near 2 degrees broad, and its summit seemed to rise nearly from 80 to 85 degrees above the horizon of the sea. The sky was singularly pure; there was no appearance of rain; and what struck me most was that this phenomenon, which perfectly resembled a lunar rainbow, was not in the direction opposite to the moon. The arch remained stationary, or at least appeared to do so, during eight or ten minutes; and at the moment when I tried if it were possible to see it by reflection in the mirror of the s.e.xtant, it began to move and descend, crossing successively the Moon and Jupiter. It was 12 hours 54 minutes (mean time) when the summit of the arch sank below the horizon. This movement of an arch, coloured like the rainbow, filled with astonishment the sailors who were on watch on the deck. They alleged, as they do on the appearance of every extraordinary meteor, that it denoted wind. M. Arago examined the sketch of this arch in my journal; and he is of opinion that the image of the moon reflected in the waters could not have given a halo of such great dimensions. The rapidity of the movement is no small obstacle in the way of explanation of a phenomenon well worthy of attention.

On the 3rd of December we felt some uneasiness on account of the proximity of a small vessel supposed to be a pirate but which, as it drew near, we recognized to be the Balandra del Frayle (the sloop of the Monk). I was at a loss to conceive what so strange a denomination meant. The bark belonged to a Franciscan missionary, a rich priest of am Indian village in the savannahs (Llanos) of Barcelona, who had for several years carried on a very lucrative contraband trade with the Danish islands. M. Bonpland and several pa.s.sengers saw in the night at the distance of a quarter of a mile, with the wind, a small flame on the surface of the ocean; it ran in the direction of south-west and lighted up the atmosphere. No shock of earthquake was felt and there was no change in the direction of the waves. Was it a phosphoric gleam produced by a great acc.u.mulation of mollusca in a state of putrefaction; or did this flame issue from the depth of the sea, as is said to have been sometimes observable in lat.i.tudes agitated by volcanoes? The latter supposition appears to me devoid of all probability. The volcanic flame can only issue from the deep when the rocky bed of the ocean is already heaved up so that the flames and incandescent scoriae escape from the swelled and creviced part without traversing the waters.

At half-past ten in the morning of the 4th of December we were in the meridian of Cape Bacco (Punta Abacou) which I found in 76 degrees 7 minutes 50 seconds, or 9 degrees 3 minutes 2 seconds west of Nueva Barcelona. Having attained the parallel of 17 degrees, the fear of pirates made us prefer the direct pa.s.sage across the bank of Vibora, better known by the name of the Pedro Shoals. This bank occupies more than two hundred and eighty square sea leagues and its configuration strikes the eye of the geologist by its resemblance to that of Jamaica, which is in its neighbourhood. It forms an island almost as large as Porto Rico.

From the 5th of December, the pilots believed they took successively the measurement at a distance of the island of Ranas (Morant Keys), Cape Portland and Pedro Keys. They may probably have been deceived in several of these distances, which were taken from the mast-head. I have elsewhere noted these measurements, not with the view of opposing them to those which have been made by able English navigators in these frequented lat.i.tudes, but merely to connect, in the same system of observations, the points I determined in the forests of the Orinoco and in the archipelago of the West Indies. The milky colour of the waters warned us that we were on the eastern part of the bank; the centigrade thermometer which at a distance from the bank and on the surface of the sea had for several days kept at 27 and 27.3 degrees (the air being at 21.2 degrees) sank suddenly to 25.7 degrees. The weather was bad from the 4th to the 6th of December: it rained fast; thunder rolled at a distance, and the gusts of wind from the north-north-east became more and more violent. We were during some part of the night in a critical position; we heard before us the noise of the breakers over which we had to pa.s.s, and we could ascertain their direction by the phosphoric gleam reflected from the foam of the sea. The scene resembled the Raudal of Garzita and other rapids which we had seen in the bed of the Orinoco. We succeeded in changing our course and in less than a quarter of an hour were out of danger. While we traversed the bank of the Vibora from south-south-east to north-north-west I repeatedly tried to ascertain the temperature of the water on the surface of the sea. The cooling was less sensible on the middle of the bank than on its edge, a circ.u.mstance which we attributed to the currents that there mingle waters from different lat.i.tudes. On the south of Pedro Keys the surface of the sea, at twenty-five fathoms deep, was 26.4 and at fifteen fathoms deep 26.2 degrees. The temperature of the sea on the east of the bank had been 26.8 degrees. Some American pilots affirm that among the Bahama Islands they often know, when seated in the cabin, that they are pa.s.sing over sand-banks; they allege that the lights are surrounded with small coloured halos and that the air exhaled from the lungs is visibly condensed. The latter circ.u.mstance appears very doubtful; below 30 degrees of lat.i.tude the cooling produced by the waters of the bank is not sufficiently considerable to cause this phenomenon. During the time we pa.s.sed on the bank of the Vibora the const.i.tution of the air was quite different from what it had been when we quitted it. The rain was circ.u.mscribed by the limits of the bank of which we could distinguish the form from afar by the ma.s.s of vapour with which it was covered.

On the 9th of December, as we advanced towards the Cayman Islands,*

the north-east wind again blew with violence. (* Christopher Columbus in 1503 named the Cayman Islands Penascales de las Tortugas on account of the sea-tortoises which he saw swimming in those lat.i.tudes.) I nevertheless obtained some alt.i.tudes of the sun at the moment when we believed ourselves, though twelve miles distant, in the meridian of the centre of the Great Cayman, which is covered with cocoa-trees.
